I find how I set up Civ 6 games, Standard Map Size Minus 1 Civ, and how I play, very very peaceful and friendly, almost all my games end up with me not engaging with warfare, sans barbarians of course, and just watching the AI have countless wars amongst themselves. Culture Victory is also my preferred vic type to go for and no War is needed for that. Whenever my neighbour declares on me I am always bummed lol This approach can work up to Emperor Difficulty but gets a bit more tricky as you go up but not impossible. Depends on who you spawn next to of course and the land etc but in general - the games I finish are the ones I have had no fights and just settled and explored and built wonders and theatre squares and just cruised to victory being friends and allied with everyone, minus the 1 leftover who will invariably hate you.
Otherwise, Journey is a good shout.
